What are the differences between Node.js cluster and fork?
Node.js cluster allows you to create multiple child processes that share the same server port, while fork creates a new process with its own memory space.
When should I use cluster over fork?
Use cluster when you want to take advantage of multi-core systems for handling more requests, while fork is better for tasks that require isolation.
Can you give an example of using cluster in a Node.js application?
Sure! You can use the 'cluster' module to create workers that listen on the same port, like this: const cluster = require('cluster');
.
What are the performance implications of using one over the other?
Using cluster can improve performance by utilizing multiple CPU cores, while fork may lead to higher memory usage due to separate memory spaces.
